Kim Kardashian — Are You Even Going to Be Around for Your Nephew's Birth?

Can you imagine not being there for such momentous family occasion?

Kim Kardashian can’t! The middle Kardashian sister freaked out when she thought big sis Kourtney’s water had broken early and she might have missed her nephew’s birth.

During a conversation via (what else!) Twitter, Kim confided to brother Rob, 22, on Dec. 10 that she was afraid she’d be on vacation during her nephew’s b-day!

“Wr r going to Ft. Lauderdale! I’m excited 2 go on a vacay with YOU! I’m just scared Kourt is gonna go into Labor while we r away,” the 29-year-old tweeted.

As it turns out, Kim has good reason to be nervous. Her sister Khloe, 25, told Ryan Seacrest early Dec. 10 that Kourtney is “due at any minute.”

She went on to tell Ryan that her sister got a little…confused….and thought she was in labor. Whoops. “She’s never experienced it,” Khloe explained. “She has no idea. She was out at lunch – this is TMI – and some fluid came down her leg and she was like, ‘My water broke. She bbm’d me and I go, ‘No, no, no, you will know. You’re fine.”

We’d put money on it that the family makes it back in time … After all, can’t the Kardashians do everything?
